4.1.2 Bridge parameters

Each bridge is uniquely described using parameters:

Bridge Identifier

Root Path Costs for the bridge ports
Port Identifier
4.1.3 Bridge Identifier
The Bridge Identifier consists of 8 bytes. The two highest-value bytes are the
priority number. The default setting for the priority number is 32 768, but the
Management Administrator can change this when configuring the network.
The six lowest-value bytes of the bridge identifier are the MAC address of the
bridge. The MAC address guarantees that every bridge has a different bridge
identifier.
The bridge with the smallest number for the bridge identifier has the highest
priority.
